标准范围

ISO/TR 5660-3:2003检查了目前用于建筑产品的锥形量热计的局限性，并建议了其他应用领域的其他类型产品克服其中一些局限性的方法。它将大量有关仪器使用经验的信息汇编成一套指南，这将有助于在更大范围内标准化锥形量热计的使用。对试样制备的各个方面以及暴露在辐射热下的试样的熔化、剥落和膨胀等行为给出了特别的指导。还讨论了试样厚度与基板使用的相关性，以及固定在基板上的方法。对测试各种“非标准”产品的方法给出了建议。对仪器的校准技术、适当热流水平的选择和点火协议提出了建议。除了向操作员提供的指南外，ISO/TR 5660-3:2003还对试验结果的表示提出了建议。

ISO/TR 5660-3:2003 examines the limitations of the cone calorimeter as currently used for building products and recommends ways in which some of these may be overcome for other types of products for other application areas. It compiles information from a large body of experience with regard to the use of the instrument into a set of guidelines which will help to standardize the use of the cone calorimeter in this wider scope.Particular guidance is given on aspects of specimen preparation and on the behaviour, such as melting, spalling and intumescing, of specimens exposed to radiant heat. The relevance of specimen thickness and the use of substrate, and methods of fixing to substrate, are also discussed. Advice is given on approaches to testing a variety of "non standard" products. Recommendations are made on techniques of calibration of the apparatus, selection of appropriate heat flux levels and ignition protocols.In addition to the guidance given to operators, ISO/TR 5660-3:2003 makes recommendations on presentation of the test results.
